Cleaned up and simplified AP decoding. Enabled AP decoding for ncontest=0 and ncontest=4 (RU) so far. Missing MyCall or DxCall or nonstandard calls will disable AP passes that wouldn't make sense.

unpack77 now returns logical variable unpk77_success, which will be .false. if there is something obviously wrong with the message. Still to do: set the flag if the unpacked message contains CQ in an implausible place.
